Abstract: scale_transformation estimates the maximum and minimum gap difference for an (ordinal) test score scale between two groups across two points of time. This program uses the Stata mata function [M-5] optimize to perform a grid search from multiple random initial parameters. Other optimization objects (i.e. correlation, R-squared and controls) are available to run various robustness checks.
